A remarkable discovery has been made in the world of microbiology: a single-celled organism, named Incendiamoeba cascadensis, can thrive in conditions hotter than any other known complex cell. This tiny amoeba, found in a pH-neutral 'hot stream' at Lassen Volcanic National Park, can grow at an astonishing 63°C, breaking the previous record for eukaryotic life by 3 degrees Celsius. This finding challenges the long-held belief that eukaryotic life, which includes all animals and plants, is not suited to extreme conditions typically tolerated by bacteria and other organisms lacking a cell nucleus. The discovery has sparked excitement among microbiologists like Angela Oliverio, who emphasizes the need to reconsider the limits of eukaryotic cells. The research, published in a preprint on November 24, was conducted by Oliverio and her colleague, Beryl Rappaport, and has the potential to revolutionize our understanding of the adaptability of life in extreme environments.
